kowach The images also look good on my end, I am not experiencing distortion to faces on images via desktop. It could be worth looking at potential WebP third party plugins, and seeing if any of those give you control over the level of compression. Just bear in mind adding a plugin then adds other script to your site, so the site would have additional latency from the new plugin on the domain. Or, you could just test turning webP off and seeing how that affects overall site speed/performance. Those would be the suggestions if you don't want to stick with the current image optimization settings
